Gotrade News - Japan's Nikkei 225 crossed the 60,000 level for the first time in history on Wednesday. The milestone was driven by a concentrated rally in artificial intelligence and semiconductor stocks.
Key Takeaways
- Nikkei 225 hit an all-time high of 60,013.98, breaching the 60,000 milestone for the first time ever
- The rally was extremely narrow, with only 17% of 1,600 TSE Prime Market stocks advancing while 78% declined
- SK Hynix posted record Q1 2026 revenue as HBM chip prices surged over 40% year-over-year
The Nikkei peaked at 60,013.98 before closing largely flat after early-session volatility. The index fell as much as 0.7% before recovering, while the Topix held steady at 3,744.93.
Early sentiment was lifted by President Trump's indefinite extension of the Iran ceasefire agreement. However, the rally was remarkably narrow, with the NT ratio hitting a record high of 15.74.
Chip stocks led the advance, with Advantest gaining 2.65% and Tokyo Electron rising 1.76%. SoftBank Group posted the biggest jump at 6.4%, reflecting strong investor optimism around its AI investments.
On the other side, Fast Retailing (Uniqlo) dropped 1.8% and was the heaviest drag on the index. A striking 78% of TSE Prime Market stocks actually declined on the same day the index hit its record.
This narrow breadth signals the Japanese market is being driven by AI thematic bets, not broad economic strength. Investors should be cautious because the index gains do not reflect overall market health.
Behind the Japanese chip stock rally lies a fundamental catalyst from the global AI memory sector. SK Hynix posted record-breaking Q1 2026 figures as High Bandwidth Memory prices surged over 40% year-over-year.
HBM3E chips from SK Hynix are sold out through at least Q3 2026. Their primary customer is Nvidia, which uses these chips for H100 GPUs and the Blackwell architecture.
The HBM market has shifted from price competition to allocation competition among buyers. SK Hynix committed over $20 billion in capital expenditure to expand HBM production capacity.
Samsung is racing to catch up with new HBM fabrication facilities expected online by late 2026. Micron remains months behind in HBM technology, giving South Korean manufacturers a significant competitive edge.
South Korea's concentration of HBM manufacturing gives it outsized strategic influence over the global AI supply chain. Indonesia's successful 172.1 billion yen Samurai bond sale further underscores broad confidence across Asian markets.
The Nikkei's run to 60,000 marks a full recovery of all losses since the late February US-Iran conflict. However, the narrow participation rate serves as a caution for investors considering entries at current levels.
